Caracterização quantitativa e qualitativa da matéria orgânica do solo em plantio direto
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em AgronomiaUTFPR, 2016-11-28)
Organic matter is a common endpoint to check the quality and sustainability of soil management. The tillage system has basic premises for the conservation of soil organic matter and in this respect grows the need to improve ...
Preparation and characterization of light-cured methacrylate/montmorillonite nanocomposites
(John Wiley & Sons Ltd, 2010-10-14)
Polymer/clay nanocomposites were prepared from dimethacrylate monomers, commonly used in dental restorative resins, and an organically modified silicate (montmorillonite). The photopolymerization process was hardly affected ...
Distribution and fractionation of the rare earth elements in Brazilian soils
(Journal of Geochemical Exploration, 2019)
Comparación de dos métodos de fraccionamiento físico de la materia orgánica del sueloComparison of two physical fractionation methods for soil organic matter
(Asociación Argentina de la Ciencia del Suelo, 2010-07)
Se compararon las concentraciones de carbono orgánico particulado (COP) y carbono sobrenadante (Cs) obtenidas por los métodos de fraccionamiento granulométrico (fracción > 53 µm) y densimétrico (densidad de licor: 2 g ...
Precipitation patterns, dissolved organic matter and changes in the plankton assemblage in Lake Escondido (Patagonia, Argentina)
(Springer, 2012-07-27)
Global warming affects the hydrological cycle by increasing the frequency and intensity of extreme rainfall events and dry spells. These changes potentially affect the quantity and quality of dissolved organic matter (DOM) ...
Estratégias de absorção e utilização de fósforo por genótipos de soja
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências Rurais, 2022-08-23)
Currently, crops such as soybeans are highly dependent on applying phosphate fertilizers. However, phosphorus (P) is a finite natural resource and proposing alternatives for P rational use is an urgent demand at a global ...
Probing the Combined Effect of Flunitrazepam and Lidocaine on the Stability and Organization of Bilayer Lipid Membranes. A Differential Scanning Calorimetry and Dynamic Light Scattering Study
(Humana Press, 2012-12-27)
Combined effects of flunitrazepam (FNZ) and lidocaine (LDC) were studied on the thermotropic equilibrium of dipalmitoyl phosphatidylcholine (dpPC) bilayers. This adds a thermodynamic dimension to previously reported geometric ...
Operational problems related to the preparation of the seawater soluble fraction of crude oil
